Application filed April 5, 1916. Serial No. 89,178.

To all whom it may concern:

Be it known that I, VVALTER J. LIDDLE, a citizen of the UnitedStates,-residing at Milwaukee, in the county of lit lilwaukee and Stateof Wisconsin, have invented certain useful Improvements in Priming-Cupsfor Motors, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to improvements in priming cups for explosiveengines, one object of the invention being the provision of a cup whichis readily attached to the engine cylinder and provided with means forre leasing the contents of the cup when it is desired to prime theengine.

A further object of this invention is the provision of a simple, durableand inexpensive device of this character which is thoroughly efficientand practical in use.

In the accompanying drawings:

Figure 1 is a sectional view through a portion of an engine cylindershowing the present cup complete as in use, the same being shown insection with the valve closed.

Fig. 2 is a sectional view through the cup with the valve open.

Referring to the drawings, the numeral 5 designates the hollow nipplewhich is adapted to be inserted in the opening 6 of the engine 7 so thatthe priming fluid may be directed into the cylinder. Carried by themember 5 is a cylindrical boss 8 having a port 9 therethrough which is acontinuation of the port through the member 5, a needle valve seat 10,being formed at the upper end thereof.

The boss 8 is eXteriorly screw threaded to receive a cap including theinteriorly screw threaded shell 11 which is carried by the thumb wheel12, which in turn supports the cup 13 which has the two ports or outlets1 1 leading therefrom so that the priming fluid will enter the chamber15 above the boss 8.

A concentrically disposed stem 16 provided with the valve 17, is carriedby the thumb actuated wheel 12 for closing the port 9 by engagement withthe seat 10. Thus when the parts are in the position as shown in Fig. 1,the priming fluid, generally gasolene, is poured in the cup 13, andafter a sufficient quantity has been placed therein, the thumb wheel 12is rotated to release the valve 17, or to assume the position as shownin Fig. 2, so that the priming fluid which was directed in the chamber15 through the ports 14, will then flow to the engine cylinder.

A tubular sleeve 153 is carried by the memher 5 and is concentric to theboss 8, the same being of a sufficient length to abut the under side ofthe wheel 12 when the parts are in the position as shown in Fig. 1. Itwill be appreciated that the sleeve serves as a protecting means for theboss and shell and in addition is engaged by the under surface of thewheel' simultaneously with the seating of the valve and limits thedownward move ment of the shell to consequently prevent distortion ofthe valve stem when the valve engages its seat.

The members 12, 13, and 11 are preferably made of fiberoid or hardrubber, but it is evident that the same can be made of metal if sodesired.

From the foregoing description, it is evident that with a priming cupconstructed according to and embodying the present invention, that aproper priming charge may be directed into the cylinder of the engine.

What I claim as new is 1. A priming cup including a nipple, a boss onone end thereof, the nipple and the boss being provided with alongitudinal port, a closure cap adjustably engageable with the upperend of the boss forming a chamber between the cap and boss and alsoprovided with means whereby liquid may flow into the chamber, valvemeans depend ing from the cap for controlling the flow of liquid throughthe port, and means on the nipple for protecting the lower part of thecap and the boss and for limiting the downward movement of the cap toconsequently prevent distortion of the valve means sub sequent to theseating of the valve means.

2. A priming cup including a nipple, a boss arranged concentric to andintegral with the upper end thereof, the nipple and the boss beingprovided with a longitudinal port the upper end of which is enlarged toprovide a valve seat, a protecting sleeve integral with the upper end ofthe nipple and surrounding and extending above the upper edge of theboss, a shell adjustably engageable with the upper end of the boss, anoperating wheel integral with the upper edge of the shell, a cuparranged on the upper surface of the wheel and provided with openings inthe bottom thereof to establish communication with the chamber, providedbetween the engageable with the upper edge of the sleeve shell Wheel andboss, a valve stem dependwhereby to limit the downward movement ing fromthe under surface of the Wheel, a of the shell and prevent distortion ofthe valve on the stem for engagement with the valve stem.
